Eric Olszewski 🇺🇸(@EricOlsz):This week, @ActinideInc became the first startup in history to enrich uranium, producing HALEU, the fuel for next-gen and small modular reactors. We did it using Endurance, a particle accelerator that we designed and built in Texas. Endurance usually produces enriched Yb-176, a precursor for cancer therapies worth roughly $30,000 per gram. After a bulk Yb-176 delivery on July 30, we reconfigured Endurance for uranium.
